...again. When I plug it into my laptop, I get an annotation telling me that the adapter's not recognized, and it will run the thing, but the battery doesn't charge, and performance takes a massive hit. The strange thing, though, is that it performs fine with no charger at all. I can charge the battery with a friend's cord, so it's not my laptop, and it worked fine when I got it, so I know it's the right kind, it just stopped working properly after a couple months of use, despite having no visible damage.
If this were the first time I'd just buy another adapter, but this is an issue I have consistently, so I'm thinking it's time for something else. Can anyone here recommend me to an outside party adapter that would be compatible with a Dell XPS 17 laptop, or possibly, as a short-term solution, a software I could use to manually signal the computer that I'm using the right kind of power cord? I've tried a universal charger before as well, and that ended up causing the same problems, but right out of the box rather than after using it for awhile.
